Detailed description
Advanced Large Geometry SIMS technology
CAMECA IMS 1300-HR³ marks a powerful breakthrough in the platform of large configuration secondary ion mass spectrometry equipment. Unlike conventional analytical systems, the IMS 1300-HR³ combines a high-density primary ion source with a large‑magnet sector field design, providing unmatched sensitivity and mass resolution. Additionally, the system is equipped with a normal-incidence electron gun that creates an electron flood for optimal charge compensation, maintaining ultra-stable signals on the surface of insulating materials in ultra-high vacuum (UHV) environments.
Eliminating barriers to micro-particle measurement and trace isotope analysis
Collecting accurate isotope information or analyzing trace elements at ppm levels has always been a time-consuming challenge in geochemistry. The IMS 1300-HR³ thoroughly addresses this difficulty through excellent 2D and 3D imaging capabilities in both microprobe and microscope modes. Samples are positioned at a sub-micron level, meeting the most stringent requirements for measuring ancient minerals (U-Th-Pb), studying stable isotopes (C, O, S, Mg...), or detecting Uranium for nuclear security applications.
Maximizing automation capabilities and data management
The system allows for a efficient processing of large analytical volumes thanks to the built-in comprehensive automated software platform. The heart of the system's software is the APM (Automated Particle Measurement) tool, which has the ability to self-identify, filter, and quantify isotopes on millions of ultra-fine particles in an instant. The data is then directly visualized using WinImage and Geochronology, minimizing data processing time and ensuring highly accurate results.
